jquery multiple checkboxes - selector not working

Question

I have tried to do a test:

var test = Array();

$('input[name=first_category[]]:checked').each(function()
{
    test.push($(this).val());
});

alert(test);

Check the last checkbox.
Refresh the page.
Alert should be empty (but is not empty, it shows me 4).

I have 5 categories and each category contains more than 10 checkboxes.

Sorry, I have updated my solution. check here for the updated solution.

<input type="checkbox" name="first_category[]" value="1" />
<input type="checkbox" name="first_category[]" value="2" /> 
<input type="checkbox" name="second_category[]" value="3" /> 
<input type="checkbox" name="second_category[]" value="4" />
<br/>
<input type="button" value="check" id="btnCheck"/>

$("#btnCheck").live('click', function() {
    var test = [];
    $("input[name='first_category[]']:checked").each(function() {
        test.push($(this).val());
    });
    alert(test);
});

Thank you for your answer! What I want is to alert only the checkboxes from first_category[].

A link to an external site is not an acceptable answer. I have copied your code from jsfiddle back into your answer. (pending peer review)
